Title: Laser beam piercing method
Inventor: KOJO AKIRA
IPC: B23K26/046
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To smoothly conduct piercing a through hole in the thickness direction of a material to be cut as the start point of cutting when shape-cutting the material to be cut. SOLUTION: The focus O of a laser beam 1 converged by a lens arranged to a laser beam torch is descended from the position apart upward from the surface of a material 5 to be cut down to the position penetrating into the inside in the thickness direction and is vibrated in a range of 2-20 Hz along the optical axis 2. When the focus is located on the base material of the material to be cut, the base material is fused and evaporated to form a recessed part 12. Next, the focus O is moved apart from the base material to stop fusion of base material, and at this state, the fused material is removed from the recessed part 12. By penetrating the focus position in the thickness direction of the material 5 to be cut while repeating this operation, the through hole 13 in the thickness direction is formed to the material 5 to be cut.

Filed: 1988-02-24
Abstract: PURPOSE:To stably perform a reset operation at the time of disconnecting a power source by providing a discharge circuit to discharge the electric charge of a smoothing capacitor by the output of a power source monitoring circuit. CONSTITUTION:The discharge circuit 4 to discharge the electric charge of the smoothing capacitor in a rectifier smoothing circuit to supply a voltage in which an AC power source is rectified and smoothed to a regulator 3 by the output RST of the power source monitoring circuit 2 is provided. When the power source is disconnected, the output RST of the power source monitoring circuit 2 goes to a low level, and the reset operation of a system circuit 1 is performed. At this time, since a transistor Q2 is turned OFF and a transistor Q1 is turned ON, a discharge resistor R is connected to the smoothing capacitor, and the electric charge of the smoothing capacitor is discharged through the discharge resistor R. In such a way, it is possible to prevent an operation to recover the output voltage of the regulator 3 from being performed even when the reset operation of the system circuit 1 is performed and a consumption current Isy is reduced, thereby, the reset operation can be performed smoothly.

Title: Etching method of silicon wafer
Inventor: TANAKA HIROSHI
IPC: H01L21/306
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To restrain generation of micro-pyramids and make an etched surface more smooth, by adding Mg to alkaline solution, when a silicon wafer manufactured by a Czochralski method is etched by using etching solution composed of alkaline solution. SOLUTION: When Mg is added to etching solution, etching speed of the etching solution to which Mg is added is lower that that of etching solution to which Mg is not added. Progress of etching in the depth direction B approximately synchronizes with the progress of etching in the lateral direction A. By adding Mg, the etching speed in the depth direction B is much reduced, and reduction of the etching speed in the lateral direction A is very small as compared with the depth direction B. As a result, micro-pyramids formed by the progress of etching in the depth direction B are eliminated together with very small defects 13 by the progress of etching from the lateral direction A. Hence the micro-pyramids are not left on the etched surface 14.

Abstract: PURPOSE:To prevent the malfunction of a trunk by connecting a PCM signal converter input terminal connected to an exchange trunk to an earth and a negative power source, and decreasing the potential conversion across a DC cut-capacitor. CONSTITUTION:The other end of a primary side terminal of a letter coil 27 whose one end is connected to a PCM(Pulse Code Modulation) signal converter input terminal 24 is connected to an earth 42 through a high resistor 41, and the other end of a secondary side terminal of the letter coil 27 is connected to a negative power source 44 through a high resistor 43. Accordingly, even if a signal state in a trunk 11 is varied from a state that the PCM signal converter input terminal 24 and a terminal 25 become negative potential and zero potential, respectively and polarity relay contacts 16, 17 operate, since the terminal 24 and the terminal 25 are connected to the earth 42 through the high resistor 41, and to the negative power source 44 through the high resistor 43, respectively, the potential conversion across a DC cut-capacitor 19 is decreased. In such a way, to a feed relay 18, a large current does not flow, and a malfunction is prevented.

Title: Flashover detector for steel tower for transmission line
Inventor: NAKAMIZO KOJI
IPC: G01R31/08
Filed: 1993-02-08
Abstract: PURPOSE:To allow downsizing and simplification of a current transformer by disposing upper and lower current transformers, each having one selected main post as the primary, between an upper arm of the main post and an overhead earth-wire and between a lower arm of the main post and the earth, respectively. CONSTITUTION:Upper and lower current transformers Cu, Cd, each having a main post T4 selected according to a criterion as the primary, are disposed between an upper arm Au of the main post T4 and an overhead earth-wire G and between a lower arm Ad and the earth. When a flashover fault occurs between a power line L1m and an arm Am, for example, ground fault current Io flows by about 24(36)% through the main post T4(T1) and by 20% through T2 and T3. When a flashover fault occurs on the side of a power line L2, 20% of the current Io flows through the main post T4. Since the currents Iu and Id flow in reverse direction through the main post T4, secondary outputs of the current transformrters Cu, Cd are connected differentially at the primary of an output transformer and the secondary output is set at 24% or 20% of the current Io depending on the sum of both currents Iu, Id, or the power line side L1 or L2 where flashover fault occurred. When the integrated value of the secondary output reaches a preset value, occurrence of flashover is displayed. Downsizing and simplification of current transformer are realized by disposing current transformers each having one main post as the primary thereof.

Abstract: PURPOSE:To make a crystal vibrator thin by hermetically sealing a plate insulator and a metal container with its cover by solder and installing a tuning-fork type crystal vibrating reed into it. CONSTITUTION:On plate insulator material 5, thin films 5a, 5c and 5d of Cr-Ni-Sn are formed. Tuning-fork vibrator 7 is vacuum-held hermetically by airtight connecting to the opening end of container 8 with copper-made cover by ring film 5a at the outer circumference. Then, glass plate 6 is connected to film 5c. Film 5d is extended to one part of the top surface from the reverse surface of glass plate 5 via the flank and then connected to film 5c at hole 5b. On glass plate 6, Cr-Ni-Sn is stacked and both top and reverse surfaces are connected together via the flank. Further, spherical protrusions of soft metal such as solder are formed at the selective positions on the bottom of container 8 and glass plate 5 so as to prevent vibrating reed 7 from touching container 8 and glass plate 5. In this way, the vibrator can be made thin.
